FREDERICK WILSON, OF ROOSEVELT, NEW YORK.

WEATHER-STRIP.

Application filed. February 28, 1917.

To all whom it may concern:

Be it known that I, FREDERICK WVILsON, a citizen of the United States, and resident of Roosevelt, in the county of Nassau and State of New York, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification.

The present invention relates to new and useful improvements in weather strips, and has particular reference to a wooden strip ada ted to be associated with window sashes.

hf y invention comprises a plurality of 00- operating members adapted when joined to form the desired air-tight joint. The cooperating members have means associated therewith to overcome any warping of the members which may be caused by damp weather.

Other improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which, for a clear understanding of the invention, should be considered in connection with the accompanying drawing, forming a part hereof, and wherein is disclosed, for the purpose of illustration, convenient and satisfactory embodiments of the invention. It is to be noted, in this connection, that minor changes in the construction and arrangement of the parts may be made without departing from the spirit of the invention or the principle of operation of the various parts.

In the drawing:

Figure 1 is a vertical sectional view showing my invention as applied to the lower sash of a window having a cooperating membe formed on the sill thereof;

Fig. 2 is a vertical sectional view of the meeting rails of the upper and lower sash with my improved strip applied, and

Fig. 3 is a longitudinal sectional view of a window frame showing mv invention as applied to the sides of the window sash and a cooperating member used in place of the common form of outer beading.

Similar reference characters indicate corresponding parts throughout the several. views in the drawing.

Referring particularly to Fig. 1 of the drawing, 1 designates a standard form of window sill and 2 the lower sash having a weather stripping designated IV in its en- Specification of Letters Patent.

tirety, the weather stripping W comprising a pair of members 4 and 5 respectively, the member 4 being carried by the sash 2, while the member 5 is carried by the sill 1. Each member includes a body portion 3 having a stepped extension 6 presenting intermediate and outer surfaces a and b respectively, the extension 6 of both members being designed to overlap each other so that the intermediate surfaces a will be spaced apart relative to each other, while the outer surfaces of said extensions at all times contact with each other in the disposition of the weather stripping IV in use with the window. The extensions 6 are sufficiently narrowed inthickness, so as to maintain the proper spacing apart of the intermediate surfaces at of themembers 4 and 5 when assembled and secured in place in a window.

The contacting of the outer surfaces 1) of the members 4 and 5 obviously avoids warping of these members and particularly at their portions throughout the spaced intermediate surfaces a.

The preferred form of my invention is set forth in Fig. 2 wherein is presented the meeting rails 7 and 8 having the cooperating weather strips of my invention formed adj acent the meeting edges thereof. The extension 4 is shown extending over the extension 6 for an obvious purpose. The spacing 9 provides means for overcoming the warping of the wood as above set forth.

In Fig. 3 I have shown one of my cooperating members 4 used in connection with the outer beading as employed on all standard window frames. The weather stripping having the extension 6 is attached along the outer edge of the side rail of the window and is slidably mounted thereon thus presenting the desired air-tight joint at practically the same cost as the forms now used.

While I have herein illustrated and described with a considerable degree of particularly constructional details of the weather strip embodying my invention, it is to be understood that the invention is not limited to the particular form and arrangement of the several parts which may be modified within a wide range without departing from the essence of the invention, the construction shown and the description based thereon being intended to be taken in an illustrative rather than a limiting sense.

I claim: faces at right angles to each other, the inter- The combination With relatively movable mediate surfaces being spaced apart, while parts, of weather stripping members, each the outer surfaces of said extensions at all 10 secured to one of said parts, said members times contact With each other. 5 having body portions provided with stepped In testimony whereof, I affix my signature extensions overlapping one another and prehereto. senting adjacent intermediate and outer sur- FREDERICK WILSON.
